. All valves for switching between sample
and test gas(es) switch identically to the predefined time-controlled sequence..
Note
When the zero point or span value is checked manually, the associa-
ted solenoid valves switch.
Note
If no valves are connected, the user must ensure that the correct test
gas is supplied manually and fed via the correct gas inlet, usually via
gas inlet W11.
The AutoCal function is not available for non-nominated device channels, marked with
“-----”.
11.3.3 Setting the mA behaviour during calibration
For better integration of the GenTwo® PMA1000 V2.4 into external control processes, the
behaviour of the mA outputs during a calibration process can be set for all instrument
channels.
Three settings of the mA behaviour during calibration can be selected. The mA output
follows the concentration of the applied test gases (setting 0), a previously defined substi-
tute mA value is connected to the output socket (setting 1) or the last mA value before
calibration is frozen and permanently displayed (settings 2, 3 and 4).
Select the following settings in the „Configuration mA during calibration“ parameter:
„
0 = no change, mA value is displayed according to the applied gas concentra-
tions and selected measuring ranges, as shown in the measuring mode
